1 Specification of Letters Patent.

Application filed January 29, 1917. Serial No. 145,262.

T 0 all whom it may concern Be it known that'I, EARL G. WATROUS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Flushing-Valves, of which the following is a specification.

My invention relates to what are known as slow closing or flushing valves for water closets and the object thereof is to provide a simple, eflicient and reliable valve of this character.

In the drawngs, Figure 1 is a sectional elevation of a flushing valve embodying my invention; Fig. 2 a top plan view thereof; Fig. 3 a sectional elevation on the line 3-3 of Fig. 2; and Fig. 4 a sectional elevation of a modified form of construction as regards the manipulative means for operating the valve.

Referring to the embodiment of my invention as illustrated in Figs. 1, 2 and 3 the valve casing is formed in two parts or sections," an upper section 1 and a lower section 2 which are secured together at meeting marginal flanges in suitable manner as by means of the screws 3, these two sections clamping between them at such flanges a flexible diaphragm 4 of suitable material. The casing is provided with an inlet pipe connection 5 and an outlet pipe connection 6. The interior of the lower section 2 of the casing is provided with a centrally arranged casing 7 which forms a discharge chamber 8 open at all times to the discharge connection 6. Within this chamber is arranged the main or controlling valve which controls the supply of the flushing water through the valve mechanism and to the water closet This main valve comprises the flexible diaphragm 4 together with a disk 9 and a sleeve 10, the latter passing through such disk and diaphragm and being secured to a follower plate 11 by screwing into a centrally screw-threaded socket thereof. Ev

preference, this plate is weighted in suitable manner to assure proper closing of the discharge valve. The sleeve 10 is provided intermediate its length with a marginal flange 1O bearing against the under side of the disk 9 whereby the latter is held clamped in position onto the under side of the diaphragm. The follower plate is preferably of the formation shown in Fig. 1 with its.

extreme upper edges 11 straight so as to is provided at its lower end with flange 10 which is of the same diameter as the disk 9 and is adapted to fit in andlsubstantially close the upper end of the dia:

phragm chamber when its uppermost position.

he main valve is guided inits movements by the provision of a central tube 12 which at its lower end screws into a socket 8 of the discharge chamber and extends upwardly within the sleeve 10 so that the latter may slide up and down thereon. If desired, this tube may be cast integral with casing 7. This tube is provided with a lateral port 12 communicating with the bottom of the discharge chamber and also with the interior of the tube as well as with the interior of the socket of the follower the main valve is in plate 11. The purpose of this arrangement is to permit of the free passage or escape of water to and from the space above such tube and thereby prevent the uum.

The inlet chamber 13 below the diaphragm is .in constant communication with the chamber 14 above the diaphragm by means of the bypass 15 which is regulated bymeans of the regulating valve 16 of the usual form with the result that the rate of flow of water through such by-pass can be regulated.

The manipulative means for operating the relief valve may be a foot and hand control" combined as shown in Fig. 1, or a hand control, as shown in Fig. 4.

Referring to the form of control shown in Fig. 1 the pedal lever 17 is pivoted to the top section of the casing on the pin 18 and is held to normal position by means of the spring 19 coiled around the two stop members 20 and 21 projecting from the lever and casing respectively, and adapted to limit the downward. or operative movement of such lever. The top of the section 1 is provided with a chamber 22 communicating with the top of chamber 14 through the port 23 and also with the discharge connection 6 through the passage 24. The port 23 is controlled by a disk valve 25 which is formation of a vac- Patented May 24, 1921.

secured to a flexible diaphragm 26 by means of the screw 27 which passes through the valve and diaphragm and screws into a plunger '28 reciprocable ina central opening in a plug 29 which screws into the top of:

section 1. The lever 17 is provided on its the chamber- 13 and the chamber 14 is sup plied with the same pressure through the bypassj15; Under this condition the parts are in their normal position shown in Fig. 1.

iVVhen; the operator operates the lever 17' by either pressing his foot upon the left-hand end thereof or pulls upwardly thereupon by means of the finger-hold or hook '31 the plunger 28 is relievedof the pressure of the finger 3O thereupon with the result that the water pressure in the chamber 14 will open the valve 25 andsuch water will escape through the port 23, chamber 22 and passage 24 to the discharge. connection 6. As a fur ther result the preponderance of pressure in the chamber 13 will move the diaphragm and its attached parts upwardly until the flange'lO is in position to close the upper end of the discharge chamber 8. When the pressure on the lever 17 is removed the valve 25 will be closed and the water under pressure will pass through the by-pass 15 and into the chamber 14 whereupon the dia phragm will be moved downwardly at a slow rate determined 'by the rate of flow through such by-pass. The water in the chamber 13;,will flow into the discharge chamber as .soon as the flange 1O has been lowered below the top opening thereof and the water will thereupon pass through such discharge chamber and through the discharge connection. When the diaphragm reaches its lowermost position the communication between chambers 13 and Swill be closed by the disk 9 and also by the diaphragm itself pressing upon the top edge of the controlling chamber. 7

Referring to the hand control shown in Fig. 4, the same comprisesa handle 32 to whose lower end is secured by screwing thereonto a collar 33 having an outer marginal flange 33*. This flange fits within the upper end of a casing 34 which is secured to the top of the upper section 1' of the main casing corresponding to the sectionrl of the other form of construction. This flange and consequently the handle is retained within the casing by reason of the inturned end flange 34% Within this casing 34 is arranged a disk 35 which is spring-pressed upwardly or outwardly by means of a coiled spring 36. This disk is secured to a valve stem 37 which extends downwardly through the stuffing box 38 and is provided at its lower end with a head 39 constituting a valve adapted to govern the port 40 which leads from the chamber 14 to the passage 24. A right spring 41 is interposed between the disk 35 and the inner end of the handle 32 in order to maintain such handle in its normal raised position shown. l/Vhen this handle is tilted to one side the depressed side of the flange 33 will contact the disk 35, ford. ing the latter downwardly against the'tension of the spring 36 and opening the relief valve 39 with the same result as the opening 01": the valve 2'7 in the otherform of construction. When the pressure o'f'the handle is released the springs 36 and 41 will restore the movable parts to their normalposi'tiou.
